      I have had a 20 gallon RCS tank for 3 years now.  I have moss balls and some JAVA moss, drift wood, and mineral rocks.
      Only RCS in the tank and some soft shell snails I have in there I breed for my fresh water puffer fish in another tank,.
      My issue is that the shrimp live 1-2 years and they breed just fine but I never see babies.  I see plenty of eggs but never babies.  (Well 1 or 2 a month maybe but they disappear)
      The adults keep going just fine until they die off of old age or something else.
      I keep about 100 shrimp in the tank and have to replenish 50 every 6 months about.
      Water Temp I keep about neutral. 
      PH- 7- 7.2
      I use distilled water or sometimes Reverse Osmosis water because our tap water goes through a water softener which puts a LOT of salt in it which makes TDS very high so I try not to use tap water at all.   
      I feed every 2 days with Azoo or other good food and not much.  Its all gone by the time I feed again.
      I do add some powder food for the babies and a shrimp bacteria powder (just started that about 6 months ago but has not helped or hurt)
      Someone told me due to the distilled water my issue is LOW TDS.  So I bought TWO different meters.  I tested the distilled water and its about zero which is correct.  I then tested my water and its about 700.   I do top offs and just did a 20% water change last weekend with distilled water.
      So is that the issue?  Should I pull out the mineral rocks?
      I am thinking tonight to take about 8 gallons of water and drain the tank down about 40% and then fill with the distilled water.   I can repeat the process in a week and once I get the TDS under 150 I can add a little shrimp mineral to get it to the 200 range.   The reason I am saying that is the TDS could be bad TDS and not the minerals they needs.  I ordered some Salty Shrimp Mineral which I heard was good.
      Should I just give up?

      Your Caridina should be fine with that PH, it may be the new substrate and setup causing it to be a bit lower than you expect but if my previous attempt is anything to go by it should creep up very slowly as the tank settles and matures! My prior tank setup started at PH5.5 and all was well, and the current setup is PH5 though the next colour change is PH6 so it could be anywhere between those figures???  Hope the berried female is still doing well, or has she had her babies yet? Babies will be microscopic and hide to start with. Simon

      My PH seems to stay so low anymore. I float around 6-6.2 at all times now. That blows my mind. Not sure why, driftwood maybe?

      The photo is not a DAS.  The only place I know that breeds DAS commercially is Aquagreen  for half that price.  https://www.aquagreen.com.au/catalog.html I do keep them and have bred them in the past but I don't have any excess at the moment.  I'm going to try and breed them again this summer.  They have marine larvae so are not easy but on the flip-side they live for 5 years or more and are hardy. The photo at that site looks to be a Paratya  which will also eat filamentous algae but not as voraciously as DAS.  My Paratya came in the mail from https://www.livefish.com.au/tropicals/shrimp-and-crays.html You can get them in local rivers but I find the ones from livefish do better in warmer tanks (Livefish are in QLD) - these breed in fresh water in your tank (easily).

      Oh no it’s magnetic... could be a problem with my magnet cleaner. Although, depending on the attraction I could just use the mag cleaner for the top 3/4 of the tank and get a scraper or something for the bottom.

      Ooh I just found a sand that looks almost perfect, it even comes in the right package size for my tank. https://www.aquaticsupplies.com.au/products/pisces-iron-sand It’s another Pisces & Oliver Knott creation; AquaIron. Says it doesn’t alter the KH/GH/pH/TDS etc. Only problem is it says it should not be added to established tanks due to... cloudiness?? What do u think about this one?  Thanks again for your guys’ help!
